Tefal Heater Not Energizing While Control Appears Normal

Multicooker timer counts down but there is no heating; food remains cold.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Open main heater element, Failed heater relay/triac on PCB, Broken wire between PCB and heater, Blown thermal fuse in heater circuit

Safety first: Unplug before any disassembly.

Check for warmth: After 5–10 minutes of a cooking program, carefully feel the outside of the cooker base. If completely cold, the heater is not energizing.
Listen for relay click: At the start of heating, you may hear a faint click. Absence of this may indicate a relay/triac issue.
Advanced check: A technician can open the base, measure heater resistance, and check continuity through the thermal fuse.
Repair: Replace the heater element, thermal fuse, or power PCB as required.
